FolderBrowseDialog is a WinForms control. Are you opening the dialog box on server side?

Richard Deeming 20-May-15 8:39am

Sounds like the answer to me!

When you're debugging in Visual Studio, it almost appears to work, but only because the client and the server are the same computer in that specific case.

That seems to cause a lot of confusion for developers who are new to ASP.NET.

What? This does not make any sense.

Member 11527624 20-May-15 8:40am

I have added the system.windows.forms assembly in my solution as a reference and so it is workinng fine.But the problem is when i click on browse it displaying the window at the back of application

It will NOT work once you deploy it on the web server. Any dialog from win forms will open on the computer running the application (i.e. web server) and WILL NOT show on the client computer. All you'll get is blocked web application (since there will be no one to close the dialog on the server)

It will work on your machine because you are web server for development. But try to publish your app on some other machine and it will block.

As the first comment says, the dialog box is appearing on the server.

It appears to work when you run the site from Visual Studio, but that's only because the server and client are the same computer in that specific instance.

As soon as you deploy your code to a real server, the dialog will appear on the server, where nobody will ever see it, and your code will hang waiting for someone to press a button on the dialog that nobody can see.

The thing is, if you deploy the application on a web server and try to access it on client, It will not work and your page will hang waiting for an input.

Currently, your client and server both are on the same machine and hence you can see the dialog box(but that dialog is actully opening on server side).

You need to have a custom control which will open on client side. Check the link below: Directory Browsing in ASP.Net 2.0[^]

Could you provide me with some code.i have checked the above link but if we gonna use that in the master page then it is opening repetitive windows and not working properly

Abhipal Singh 20-May-15 9:17am

What are you trying to achieve by browsing the folder paths?

Are you are trying to upload files from client machine?

If yes, then use FileUpload asp control. Its straight forward. You just have to drag and drop it on your page.

Member 11527624 20-May-15 9:24am

NO i am saving the folder path in one table and files in the folder path into another folder what user has selected into another table and displaying it according to the selection of the user from UI.

@SA: Thanks for upvoting :)
@Member 11527624: I am afraid there is nothing ready made for folder browsing in ASP. However, there are a lot of open source code available on internet all you need to do is search one and make it fit in your application. People have made custom controls for this purpose.
The best example I can quote is of Telerik(its paid though).

Member 11527624 21-May-15 7:37am

Thanks to all who gave me the replies but i am in an ambiguity whether without using the paid softwares my problem could get solved or not.I want the dialog box opened to be on the top of aplication but it is opening on the back.Then i have to minimize my application and select.I want the solution for that.

Abhipal Singh 21-May-15 7:50am

As everyone said... the dialog box you are seeing is poping up on "the server side".

I request you to deploy your application on one computer (Web Server) and try to access it on another computer(client) to see what we all mean.

After you complete this activity, you will be in a better position to understand the issue correctly. Repost, if you are still not able to solve your issue.

Member 11527624 21-May-15 7:52am

Yea i got your point.. Thanks

Abhipal Singh 21-May-15 7:59am

You are most welcome :)

Feel free to ask any other query if you have!

Member 11527624 21-May-15 8:44am

Yeah sure!!One more question regarding this when i am using this code and selecting D drive folder it is saving the path in the database in c drive only.I am doing R&D on that.Could you just run this code and let me know why it happens?

Abhipal Singh 21-May-15 8:50am

Have you debugged?
attach a debugger and see the value you are getting in fbd.SelectedPath in your code.

Note: Just reiterating using FolderBrowserDialog is entirly wrong approach in your case. So don't debug and fix this issue.

Member 11527624 25-May-15 5:25am

ok.I can save the particular directory path
for eg.If i selectd D:\ it is getting saved as D:\ in directory table
but it is showing as c:\ and the list of files in the D:\.
It is only showing C:\ in the respectory files table.I dont know y.Could u please help..

Abhipal Singh 25-May-15 5:53am

How are you getting those file paths?
I believe by using a custom component.. If Yes, Then have you tried to debug the custom control you are using to fetch the Directory and its files? What are the results?

Member 11527624 26-May-15 3:34am

I am reading the file paths from the stored procedure and displaying in the grid view with respect to the directory id(Primary key).I am not using any custom component.
I have written 2 stored procedures for reading the directoy information and reading of the fiels in the directory.

Abhipal Singh 26-May-15 5:02am

I dint get you... It looks like you are following a new approach..?

It would help if you could summerize everything and explain your new approach(the way you are using SPs and stuff)...

Member 11527624 26-May-15 5:13am

is there any mail id to be in touch with you.So that it would be better i guess.

Member 11527624 26-May-15 9:21am

My problem gets solved thanks all :)

Abhipal Singh 26-May-15 12:13pm

Glad you figured it out :)
